Row Details
Row Details can be enabled by providing a <template class="row-details">
and expanding/collapsing items by using {{expanded}} template variable,
expandedItems property or expandItem(item) and
collapseItem(item) methods.

Expanding Items Without Data Binding
In this example the grid's activeItem property is bound to expandedItems property.
Hint: Click a row to toggle the active item.
